What are soaler panels made of?

Solar panels are primarily made of photovoltaic (PV) cells, which are typically composed of silicon. Silicon can be found in various forms, including monocrystalline, polycrystalline, and thin-film. These PV cells are encased in protective materials such as glass and a backsheet, which help shield them from environmental damage and enhance their efficiency in converting sunlight into electricity. Additionally, components like aluminum frames and junction boxes are used to support and connect the panels.
